Abstract
The monitoring of a complex industrial scale process is a challenging task, particularly when such a process is a large (100m3) industrial organic waste anaerobic digestion (AD) system. This paper describes the deployment of fibre optic based sensors for monitoring an AD process. To enable this complex process to proceed, a number of critical conditions must be set (e.g. temperature, pH etc.).Two novel fibre optic sensors have been developed for monitoring temperature and pH. These operate in a zone zero environment (highly explosive) and need to withstand vibrations and microbial activity and to operate over extended periods of time (months) with no or little servicing.
